Sandbox memory disclosure via uninitialized GPU resource
Published Aug 18, 2026 · Updated Aug 19, 2026
Information disclosure in GPU in Google Chrome before 151.0.7922.169 allows remote attackers with renderer compromise to read memory outside the sandbox. The public record identifies the flaw as use of an uninitialized GPU resource that can expose stale memory contents when crafted HTML reaches the affected GPU path, but Google has not published the specific object or function. A separate renderer-process compromise is required first, so triage centers on post-compromise sandbox-crossing memory disclosure rather than standalone code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
